紫外均匀曝光对长周期光纤光栅耦合特性的影响
Effect of UV Uniform Exposure on Coupling Characteristics of Long-Period Fibre Gratings
摘要
写于载氢光纤上的长周期光纤光栅经过高温退火后,对其进行紫外均匀曝光能够有效改变其耦合特性。随着曝光量的增加,其共振波长向长波方向移动,共振峰强度先增大继而减小。并对此给出了理论解释。
Abstract
UV uniform exposure can effectively vary the coupling characteristics of the annealed long-period gratings (LPGs) in hydrogen-loaded fiber. With the increase of UV exposure, the resonance wavelength shifts toward longer wavelength and resonance peak intensity increases first and then decreases. A theoretical explanation for this phenomenon has been given.
